A portion of the financial internet spent a portion of yesterday discussing a pretty silly chart showing that the performance of the Dow from 2012 through now has been exactly like the performance of the Dow from 1928 through September 1929, and since those who do not learn from charts are doomed to keep drawing them, that means we're headed for an October 1929-style crash.
